Description

A kind of wind-power electricity generation buoyant foundation
Technical field
The present invention relates to Oversea wind power generation field, in particular, relate to a kind of novel offshore wind farm buoyant foundation being applicable to deep-sea.
Background technology
Along with the day by day exhaustion of traditional fossil energy, wind energy is rapid as a kind of clean energy resource development in recent years, and wherein Offshore Wind Power Generation Technology has great development prospect because of advantage tools such as its wind speed are stable, wind shear is little, distance load center is near.But usual adopted pile foundation equipped by offshore sea waters wind-power electricity generation or gravity type foundation is very responsive to marine site change in depth, be difficult in the marine site that the depth of water is larger meet safety, stable, economic and environmental demands.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, a kind of a kind of wind-power electricity generation buoyant foundation of being intended to design for solving the problem is provided, the present invention can solve the stable problem of wind-power electricity generation buoyant foundation, the depth of water larger marine site effectively, this buoyant foundation structure is simple, reliably reasonable in design, load-carrying capacity is strong, adaptable to marine site topographic and geologic condition, has very strong practicality.
The object of the invention is to be achieved through the following technical solutions: a kind of wind-power electricity generation buoyant foundation, comprise the tower cylinder with enter hole, tower cylinder upper end is connected with blower fan, the lower end of described tower cylinder is fixedly connected with floating drum by flange, described floating drum is bowl-shape frustum cone structure, the periphery of described floating drum is provided with support beam, the inside of floating drum is provided with framework beam interconnective with described support beam, be provided with bottom floating drum is ring, described system ring is connected with the suction anchor going deep into seabed by hawser, described floating drum is also provided with the staircase structure extending to described enter hole.
Described staircase structure comprises the stair being arranged on floating drum inside and the side hanging ladder be arranged on above floating drum.
Described floating drum is hermetically-sealed construction.
Described floating drum top is set to the domatic structure that centre is high, surrounding is low.
Described hawser is tension tendon.
Firm triangular structure is interconnected between described framework beam.
Compared with prior art, the beneficial effect that technical scheme of the present invention is brought is:
1. to be ring bottom buoyant foundation of the present invention by steel cleat firmly is connected with the suction anchor going deep into seabed, even if also can ensure that in comparatively large, that waters the is wide area of the depth of water offshore wind generating normally runs and reliable and stable.
2. the present invention can install and use in the marine site that the depth of water is larger, is conducive to environmental protection, it also avoid the adverse effect of seabed silt to base fixed simultaneously; And steel cleats, length can rise and fall with bottom topography and make respective change, also can apply under the topographic and geologic condition of seabed change.
3. integrated model of the present invention has certain elasticity, allow to produce certain displacement deformation, space simultaneously in buoyant foundation is fully utilized, the layout place of transmission system of both can having powered as blower fan, refuge can be stopped again, for National Sea development of resources provides convenient as Jobs on the sea personnel;
4. simplicity of design of the present invention generally, degree of safety is high, and structure respectively to the even same sex of carrying, has good comformability to ocean environmental loads complicated and changeable, has good safety and applicability.
